Can you help me fire attachments to my primary weapon (rifle) Twice I have had the z25 Airburst & 3 times the frag laucher that attach to my rifle. I could have used them in place of crawling 600 meters to get away from the Tangos at a given time.

I have joined over a 2 weeks ago & asked this question, still no answer.

Thanks
